> It is desirable to be able to bulk update connection settings. Specifically, 
> the settings for FlowFile Expiration, Back Pressure Object Threshold and Size 
> Threshold. These settings may have been set initially by inheriting the 
> default values specified at the process group level. After initial build-out 
> of a flow, it may be determined the default settings need to be updated. This 
> requires going to dozens or perhaps hundreds of connections individually to 
> update.
> A new option to bulk update all connections would make the process easier, 
> less time-consuming and less error-prone. This feature would be similar in 
> convenience to the bulk operation of "Empty All Queues". 
> Since it is being applied in bulk, a warning/confirmation pop-up should be 
> displayed - again, similar to the "Empty All Queues" option.
> For each of the above mentioned Process Group settings (expiration and 
> backpressure object/size), two checkboxes should be presented: one for "Apply 
> to all existing Connections" and one for "Apply to child Process Groups". 
> Apply to all existing Connections: This option would update all existing 
> connections in the current and all child process groups.
> Apply to child Process Groups: This option will update the default settings 
> of the current and all child process groups without modifying any existing 
> connections.
